The battery pack 300 is arranged on the bottom plate 100 , and the convex rib 110 is located between two adjacent battery packs 300 . The tops of the two adjacent battery packs 300 are connected by a connector 200 .

[0034] In this embodiment, a convex rib 110 is provided on the bottom plate 100 to enhance the structural strength of the bottom plate 100, and the convex rib 110 can also serve as a spacing for two adjacently placed battery packs 300; and the two adjacent battery packs 300 can be connected and fixed by a connecting member 200, so that at least two battery packs 300 form a whole; therefore, the battery mounting assembly 10 provided by the utility model has a simple structure, is easy to install, and has a strong overall structure and stability.

[0035] Optionally, the connecting member 200 is an insulating structural member with relatively high strength, for example, the connecting member 200 may be an epoxy board.

[0037] In this embodiment, the rib 110 and the bottom plate 100 are integrally formed. The separating section 111 and the two connecting sections 112 together form a "ji" shape, which can effectively improve the structural strength of the bottom plate 100 and also play a role in separating and limiting two adjacent battery packs 300.

[0038] Further, limiting portions 120 are provided on both sides of the bottom plate 100. The extending direction of the limiting portions 120 is the same as that of the rib 110. The limiting portions 120 and the rib 110 limit the battery pack 300.

[0039] In this embodiment, the number of ribs 110 is one, and the rib 110 is located at the midline position of the bottom plate 100. The two limiting portions 120 are located on both sides of the bottom plate 100 with respect to the rib 110. Therefore, the two limiting portions 120 and the rib 110 together enclose two areas for placing the battery packs 300, that is, the limiting portions 120 and the rib 110 can effectively limit the battery pack 300 in the horizontal direction, avoiding the relative sliding of the battery pack 300 with respect to the bottom plate 100, thereby improving the overall package strength and stability.

[0040] In this embodiment, the limiting portion 120 and the bottom plate 100 are integrally formed.

[0041] Specifically, the limiting portion 120 has a tube structure, and the limiting portion 120 is provided with a plurality of mounting holes 121 for installing a housing through fasteners.

[0042] In this embodiment, the battery mounting assembly 10 usually further includes structures such as a housing. Therefore, a plurality of mounting holes 121 are provided in the limiting portion 120 to facilitate the installation of fasteners in the mounting holes 121, so that the bottom plate 100 and the side plate are firmly connected, improving the overall package structure stability and structural strength.

[0043] The limiting portion 120 has a tube structure, and its cross-section is in a "mouth" shape, with high structural strength, which can further improve the overall package structure strength.

[0045] Further, the bottom plate 100 is further provided with a plurality of grooves 130, and the plurality of grooves 130 extend along the length direction of the bottom plate 100.

[0046] In this embodiment, the cross section of the groove 130 is V-shaped, which can effectively improve the structural strength of the bottom plate 100 .

[0047] Furthermore, the battery mounting assembly 10 further includes at least two end plates 400 , and the at least two end plates 400 are respectively disposed at the ends of the at least two battery packs 300 in the length direction of the bottom plate 100 .

[0048] In this embodiment, both ends of the battery pack 300 are connected to the end plate 400, and the end plate 400 and the multiple battery cells in the battery pack 300 are fixed by strapping, which can effectively improve the structural stability of the battery pack 300; not only that, the end plate 400 can also play a role in protecting the battery pack 300.

[0049] Furthermore, the connector 200 includes a first connecting portion 210 and a second connecting portion 220 connected to each other, the first connecting portion 210 is connected to the tops of two adjacent battery packs 300, the second connecting portion 220 extends in a direction perpendicular to the first connecting portion 210, and the second connecting portion 220 is respectively connected to the two end plates 400.

[0050] In this embodiment, since the end plates 400 are disposed at both ends of the battery pack 300 , the connection portion is in an I-shape, that is, both ends of the first connection portion 210 are respectively connected to two perpendicular second connection portions 220 .

[0051] By connecting the first connection part 210 to the top of two adjacent battery packs 300, the battery pack 300 can be effectively fixed, and by connecting the second connection part 220 to the end plates 400 provided on the two battery packs 300, the battery pack 300 and the end plates 400 can be effectively fixed and connected, thereby improving the structural strength and stability of the battery pack 300 and the entire package.

[0052] Furthermore, the battery pack 300 includes a plurality of battery cells, and the plurality of battery cells are all glued to the bottom plate 100 , so that the plurality of battery cells are firmly mounted on the bottom plate 100 .

[0053] Furthermore, the bottom plate 100 is manufactured by a rolling process.

[0054] In this embodiment, the ribs 110 , the grooves 130 and the limiting portions 120 provided on the bottom plate 100 are all manufactured by a rolling process. The process is simple and low-cost, and the bottom plate 100 thus manufactured has a high structural strength.
